"Incyte hired The Griesser Group (TGG) to perform project related statistical work for one of our key submissions and we were extremely pleased with their work. Due to a disease-related situation with a key staff member, TGG had to pick up the job on short notice, "on the fly", in order to lead it to successful completion. We were extremely pleased with both the decisiveness and leadership provided, combined with the hands-on attitude by key TGG staff member(s). If we ever hit a similar emergency, I would call TGG immediately."
